Working with Large Data SetsIn each of Exercises, use the technology of your choice to decide whether you can reasonably apply the correlation t-test. If so, perform and interpret the required correlation t-test(s) at the 5% significance level.U.S. Presidents.

Pearson correlation statistic is only valid when the relationship between the two quantitative (continuous) variables is
TRUE OR FALSE. a. tau in rank correlation of ordinal data is best used when there are a few number of samples. b. increasing the sample size in non-parametric tests has no effect in the efficiency of the test in comparison to parametric test.
TRUE OR FALSE. a. Pearson correlation coefficient is an example of a non-parametric test. b. Though non-parametric tests are generally less efficient than their parametric counterparts, this can be compensated by increasing the sample size.
You would like to test whether you can predict the amount of rain that falls on a given day from the amount of dancing a person does the day before. You randomly sample 50 people and record both dancing and raining, taking the average for each person over a 100 day period (one value for both dancing and rain per person). Each person was located in a different city more than 100 km distant from the closest other participant, to eliminate spatial autocorrelation. Neither your rain data nor your dancing data are normally distributed. What is the best solution? a) Transform both variables using the best transformation for each b) Transform both variables using the same transformation c) Focus on transforming your dancing data, searching for a transformation that improves normality d) Focus on transforming your rain data, searching for a transformation that improves normality

It is expected that students who consistently performwell in major tests, quizzes, assignments and seatworksin the classroom also perform well in standardizedachievement test. A teacher decided to examine thishypothesis. At the end of the academic year, sherandomly selected 10 students from her class. Shecomputes a correlation between the student’sachievement test scores and the overall GPA for eachstudent computed over the entire year. The data for the10 students from her class are provided below.
